1. What are the roots of - 2x + 2?

2. The number 16 has four fourth roots. In other words, there are four complex numbers that can be entered in the square in the equation below:Find them. Please

Step-by-step explanation:

1) Given quadratic expression is

First equate the given expression to zero then we will find the roots.

Since the given equation is quadratic hence it has two roots.

For the quadratic equation we have that

Therefore roots here a and b are coefficients of respectively and c is a constant

here a=1 ,b=-2 and c=2

Now Substitute the values in we get

Therefore and are the roots of the given quadratic equation.  

2) Given that the number 16 has four roots.In other words, there are four complex numbers that can be entered in the square .

Let x be the given number 16

i.e., x=16

( by using the formula )

( by and )

Therefore

Since powers are same we can equate the bases ( bases are equal )

Therefore x=2i,2i,2i,2i are the roots of the given number 16 and they are complex numbers too
